Ah, but you didn't actually mention using Classic :). Then you are right, each application would, in theory be able to get a maximum of 2 GB each. On the other hand, Firebird won't use the memory it doesn't need.

> We see these processes with maybe 5 to 20 MB RAM each.

Which sounds about normal. And with 200 connections, that is 1 to 4 GB of memory use. You might want to look into what is being swapped in and out.
